Through the study and analysis conclude as follows : in human dna sequences , if the distinction of the number of the four bases is very small , they can distribute in a sphere whose radius equal to 1 / 4 ; if the distinction of them is comparative large , they can distribute between the sphere and the frustum - octahedron ; if one is 0 in them , they can distribute between the frustum - octahedron and regular - octahedron ; if the distinction of them is especial large , they may distribute in the outer of the regular - octahedron
通过研究和分析得到结论为：在人类dna序列中，如果四个碱基的数目相差很小时，它们可能分布在半径为1 / 4的球内；如果相差比较大时，它们可能分布在这个球和截角八面体之间；如果在四个碱基数目中有一个为零时，那么它们有可能分布在截角八面体和正八面体之间；如果相差的特别大，甚至有可能落在那个正八面体的外部。
The annihilation of the octahedron voids at the tips of fpds was divided two processes : ( 1 ) the oxide on the void was removed by the out - diffusion of oi in the shallow region , especially the oi aroud the void and by the entry of the interstitial si atomics . ( 2 ) the void without oxide shrinked by emitting vacances and the migration of silicon atoms from edge to the bottom of void
Fpds端部八面体空洞的消失分为两个阶段： (一)覆盖在空洞各个内壁上的氧化膜由于高温下硅片表面区域的间隙氧原子，尤其是空洞型缺陷周围的间隙氧原子的外扩散及自间隙硅原子的进入，而逐渐变薄直至最终消失。 (二)无氧化膜的空洞，在高温下发出一个个空位，同时八面体空洞周围的自间隙硅原子不断的从空洞的边缘迁移至空洞的底部，使空洞逐渐变浅直至最后消失。
